THE 31 APRES

The 30-40 is a game in which the mathematical advantage of the Bank is not costant. When the game starts, this advantage is about 1.096%. But SUCH ADVANTAGE can decrease till 0!

For example, if we consider an extreme case, if there would be inly odds cards, the probability to reach 31 will be 0! And the game would be null.

We have significant advantage variation only if we consider the last 52 cards.

If these 52 cards would be well-balanced the advantage of the Bank will always be 1.096%. The removal of just one card would bring slight variations on the game tax. The following schedule shows us the game tax on 51 cards, considering that the removed card is the one of the line we're analysing. For example if we should remove an Ace from the pack of cards, the advantage of the Bank will decrease from 1.09 till 1.03!

NOTICE: IN THE HISTORY OF 30-40 this is the first time a schedule about these percentages has been published.

The removal of single cards from a pack having less than 52 pieces, will bring more significant variations. Cards combination can increase these variation too.

The knowledge about how the advantage of the Bank can change will surely be useful to the player who will decide to speculate upon this game.
